UNITED *s'luafrizs PATENT oFF-ICE oTToB. WIL'LI, oF MONTGOMERY CITY, MISSOURI This invention relates to knob holding devices, and particularly a holding device for securing knobsfto covers for` pots, kettles and kthe like, the object beingl to provide an iniproved construction wherein the knob is permanently held in place without any of the holding means coming in "Contact with the hand when the knob is grasped. i

Another object ofthe invention is to provide a holding device for knobs which `may be readily screwed into place and which is automatically locked against accidental removal. v j f A further object of the invention is to provide an improved connectingl device for connecting knobsto covers, the structure being such that part of the device may be made integral witlnthe cover or separate and clampedA thereto simultaneously with the ysecurin, ,1fv of the knob in place.r`

Referrin'gto the accompanying drawings l l indicates a knob of wood, libre orother. desired material. This knob may be of any desired size and isadapted to be of a size to be readily grasped while part thereof isformed so as to receive a sheathing cup 2. `This cup i is externally-threaded, or rather, is made of thin material and formed yso that the walls p xNoB-A'rrAcIIING DEVICE v limitation inea February 21, 1929.

will present a thread for fitting in the threaded part of a lowercup or socket. By forming the'walls of jcup 2 as threads it vmay be screwed onto threads formed into the wood or other material of knob l, whereby a tight connection is provided between the two members. Preferably the knob l is provided'with an annular overhan'ging portion 4 which .presses against the lid 5, as shown in Figure 2. When the cup 2 hasl been screwed into position, as shown clearly in Figure 1, the socket 3 is pressed from the lid or cover 5 and is therefore integral therewith. This structure is preferable where the invention is being applied to a` new cover. lVhere it is applied to an old cover a different form is provided, as shown in Figures 6. and 7 ,which will be fully described hereinafter. The socket 3 is provided with a number of pressed-up portions 6.` As shown in Figure 4,-there are two pressed-up portions 6, though-one may be used, or. more than two. Preferably two are provided, as this number is comparatively easy to make and performsthe desired function. The bottom 8 of the cup 2 is provided with a number of pressed-out portions 9 similar to portions 6 butin the opposite direction.
